What part of speech further?

"Further" can be two different parts of speech, depending on its usage:

* Adverb: Used to indicate a greater degree or extent.

* Example: "We walked further down the road."

* Adjective: Used to describe something as being at a greater distance or to a greater extent.

* Example: "The further we walked, the more beautiful the scenery became."

It's important to look at the context to determine which part of speech is intended.
